I recently discovered 30+ beetles in my store bought bread crumb container. Under my microscope and hand lens, I learned that this is a very common pest of stored food, Stegobium paniceum, otherwise know as the "Drugstore Beetle". They are very small, and can pass as a flax seed. They are not harmful to humans but, my wife was utterly disgusted they they were munching away in our pantry. We ended up doing a major clean of our cupboards. I think I might have found another species, the Cigarette beetle but, still working on the id.
